Definitions
- the present invention relates in general to heated tools, and in particular to a new and useful heated tool for soldering objects to a plurality of pads which are spaced apart by a certain spacing, the heated tool including spacer bars for isolating the pads from each other.
- the heating tools may either be moved to the objects to be treated or connected, or mounted in a fixed position with the object to be treated or connected being brought to the heated tool.
- Thermal energy is either supplied to the objects to be treated or connected, by radiant heating from heated surfaces of the tool, or by direct thermal contact between the heated tool and the object. A controlled force is usually applied against the object by the heated tool.
- An additional thermal conductive material may be used to increase heat flow from the heated tool to the object. Flux, for example, may be provided for increasing the transfer of heat and for reducing oxidation during the thermal process.
- Such tools may supply heat either continuously or during selected time periods only. Heat may be applied during heating pulses which may be activated or controlled by various external conditions, for example, by forcing the heated tool against the object to be heated or connected.
- Hot gases and/or electric current for example may be used for heating specified heat supplying areas or surfaces of the tool.
- a known generally U-shaped heated tool is disclosed in German Pat. reference No. 2,848,519.
- This heated tool is mounted to holders either using screws or by welding. This keeps the heat supplying areas of the tool in position and further is used to provide electrical connectors for feeding electrical heating current to the tool.
- Such tools can be manufactured using sheet metal designs (see German Pat. Nos. 3,144,048.7, 3,137,859.5 and 3,137,860.9 to the present inventor). These heated tools can also be machined from solid materials.
- force-controlled thermal contact for transferring thermal energy from a tool to a part must also be accurately controlled. For this reason force-controlled thermal contact has limited applications. Objects having high thermal conductivity, for example objects made of metal oxides, require different procedures. Continuous preheating for example may be necessary for such applications. A heating tool is simply set at a much higher temperature to compensate for thermal loads. This has limitation however in that excess heat may be damaging to some materials.
- An object of the present invention is to provide a heated tool which can join two or more parts together by thermal treatment and which can reduce or illiminate solder-bridging of parts or areas which are located close to each other.
- the parts of electric components which are to be joined by solder or similar materials can be positioned to within only certain spacings from each other. Closer spacings cannot be utilized since solder may flow between the parts causing undesirable bridging and short circuits. This occurs when conventional heated tools having flat heating surfaces are utilized.
- Another object of the present invention is to provide spacer bars on the heating surface of the heated tool which are shaped to match or compliment the spacing between the parts that are to be soldered or otherwise heat treated. This prevents the undesirable flow of solder from one part to the other during the heating cycle.
- the spacer bars can be formed as one piece with the heated tools or can be added on as additional structures onto the heating surface of the heated tools.
- the spacer bars can be made of materials having different properties than the material of the heating surface. Materials having different thermal properites (such as low conductivity) or wetting capabilities can be used. Lower temperatures can thus be supplied to areas between the parts that are to be soldered, to reduce the flow of heat to these areas. By selecting wetting properties, the flow of solder to the areas between the parts can also be reduced.
- Spacer bars with special shapes and special thermal properties can thus be provided on the heated tool. Higher or lower temperatures can be provided across the heated tool and its spacer bars to advantageously and closely control the flow of solder.
- FIG. 1 is a fragmentary side elevational view of a heated tool in accordance with the present invention for connecting a flat cable having four wire or wire bundles to four pads of a circuit board or substrate;
- FIG. 2 view similar to FIG. 1 showing a further embodiment of the invention having differently shaped spacer bars;
- FIG. 3 is a fragmentary enlarged cross-sectional view of an area of tool having differently shaped spacer bars made as one piece with the heating surface of the tool;
- FIG. 3A is iew similar to FIG. 3 of an embodiment of the invention wherein the spacer bars are made as separate pieces from the heating surface of the tool;
- FIG. 4 is a perspective view showing the manner of connection to a circuit board in accordance with the invention.
- FIG. 5 is the assembled cable connection
- FIG. 6 is a fragmentary side elevational view of a further embodiment of wherein the cross-sectional shape of the heated can be selected for controlling the amount of heat being supplied to various areas;
- FIG. 6A is a view similar to FIG. 6 of a still further embodiment of invention.
- FIG. 1 the invention embodied in FIG. 1 comprises a heated tool 1 having a non-flat heating surface la which is provided with a plurality of spacer bars 3. Electrical current and pressure is supplied to the heating surface la by a pair of connector bars 2, 2.
- the heated tool is particularly useful for connecting an insulated flat cable 4 having a plurality of wire or wire bundles 5 that are spaced from each other by an insulated web 6, to connector pads 7 which are spaced apart by a pitch 9 on the surface of a substrate or a circuit board 13.
- Each pad 7 is provided with a coating of solder 8 for connecting the wires 5 to the pads 7.
- a section of cable 4 which is to be connected to pads 7 is stripped and rendered free of insulation to expose the wires 5.
- the pads 7 to the wires 5 tool is heated in its heating area, as schematically illustrated by crosses 11 and brought down under pressure in the direction of arrows 12 onto the wires 5.
- the heating causes the solder to melt. Because of the existence of spacer bars on the heating surface, the solder is precluded from flowing from one pad to the other. The flowing solder is blocked and dammed by the spacer bars as shown at 10.
- FIG. 2 also illustrates that the spacer bars can be differently shaped.
- Spacer bar 3a can, for example, be broader than the space between the pads and narrow in the vertical direction so that a solder connection is made without contacting the spacer bar 3a with the top surface of the pads.
- the spacer bar 3b can be narrow and deep to engage fully between the pads.
- a pitch 9 of 1.27 mm or less can be achieved. This corresponds to an equally small pitch for the wires 5 in the cable 4. As noted above, this is achieved without the danger of solder bridging between adjacent pads.
- FIG. 3 illustrates an embodiment of the invention where one of the spacer bars is provided with a plating or coating of material 16.
- Material 16 can be selected to have certain advantageous properties. For example, a material having low thermal conductivity can be selected for decreasing the amount of heat transferred to the areas between the pads. Alternatively, the material can have a higher thermal conductivity for increasing the amount of heat provided between the pads.
- Spacer bar 15 of the long narrow type may also be utilized for almost touching the board 13 to physically separate the pads from each other.
- FIG. 3 shows the example of the invention wherein the spacer bars are made as one piece with the heated tool.
- FIG. 3A includes a spacer bar 31 which is connected to an otherwise flat heating surface 1a, for example by welding.
- Another spacer bar 32 can be connected into a slot 14 provided in heating surface 1a.
- the materials of the spacer bars 31, 32 can be selected for desirable properties such as heat transmission or wetting. Material which has low wetting affinity for solder may be desirable to avoid the flow of solder between the space between pads.
- FIG. 4 shows a manner of assembling and connecting the cable 4 to a circuit board 13 which is provided with holes 19 for receiving the arms of a cable clamp 18.
- cable 4 with areas of wires 5 stripped is brought down in the direction of arrow 211 onto pads 7 which are precoated with solder 8.
- the heated tool 1 is then brought down onto the wires and pads in the direction of arrow 212 and supplied with electrical current sufficient to melt the solder. Spacer bars 3 prevent flow of solder between pads.
- the heated tool 1 is then removed and the solder solidifies.
- Clamp 18 is then brought down in the direction arrow 213 into holes 19 to firmly clamp cable 4 to circuit board 13.
- FIG. 5 shows the assembled connection
- FIG. 6 shows another embodiment of the invention wherein the heated tool 1 has a non-flat configuration with areas having different cross sections.
- a lower cross section increases the resistance to electricity and would increase the temperature of the heated tool in this area.
- small cross sectioned area 21 can be provided at the spacer bar and can be dimensioned to contact the surface of adjacent pads at 23. This helps transfer heat directly to the pads thus improving and increase the rate at which the solder melts and the connection is made.
- an additional projection 22 may be provided at the bottom of the spacer bar 21.
- FIG. 6A shows a version of the invention wherein each of the spacer bars is solid and touches adjacent pads at 25. Again, heat is transferred to the pads, but less heat is provided since the spacer bars have a greater cross section than the remainder of the heated tool.
